Hi!

We found that Microsoft Azure work in "Preview mode" Message wneh we connect to Azure:
"You've enabled preview mode for Azure IoT Hub to try new features, and existing features may not work properly. Don’t use this IoT Hub for production environments."
Now, when Azure is in Preview mode, our systems stop sending messages to IoT. And Idea, how to fit this issue?

Thank You!

    Hello @Slavko Bradac ,

    yes, the Azure IoT Hub offers a preview mode that offers eg.:
    MQTT 5

    • ECC server certificate
    • TLS fragment length negotiation
    • X509 CA chain support for HTTPS/WebSocket

    This preview mode is enabled when the related checkbox is checked while creating an IoT Hub.

    It cannot be undone afterward, you need to delete the whole IoT Hub and create a new one without this feature enabled,

    That is why it is not mended for production, for devices whose data your business depends on...

    If you have used a Device Provisioning Service, you can offer a seamless solution for the already connected devices so these can move over to the new IoT hub without losing (significant) messages (depending on the logic on your device).

    Otherwise, you have to visit each device to provide it with new credentials to access another IoT Hub.

    I'm not sure why devices have stopped sending messages. Is this happening for all devices?

    I recommend investigating the current connection first, perhaps it is just a simple network issue or expired certificate...
